Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a method and a method for producing a cushioning sheet in which a powdered agent such as a desiccant, an insecticide, an aromatic agent, a rust preventive agent or an adsorbent is enclosed. Regarding the device.

[Prior Art] Conventionally, a powdered medicine such as a desiccant, an insecticide, an aromatic agent, a rust preventive, and an adsorbent is packed and packaged using an air permeable membrane and used for each purpose such as drying and insecticide. Has already been done.

[Problems to be Solved by the Invention] However, although the above-mentioned filling package using only the periodic membrane has no buffering property and thus has a medicinal effect, it is used as a material for carrying and packaging various products. There was a problem to do.

[Means for Solving the Problems] Therefore, as a result of various studies, the present inventors have found that when filling and packaging a powdered drug such as a desiccant, an insecticide, an aromatic agent, a rust preventive, and an adsorbent, a foaming buffer is used. After crushing the air bubbles in the heat-sealed part of the flexible sheet in advance, a functional packaging material that has both the characteristics of the drug and the cushioning effect as a packaging material can be obtained by producing a foaming cushioning sheet and a breathable membrane. The present invention has been found to be obtained, and the present invention has been achieved.

That is, according to the present invention, there is provided a method for producing a powdery drug-containing buffer sheet by encapsulating a powdered drug in a bubble-buffering sheet and an air-permeable film as heat seal, the method comprising: After crushing air bubbles at the position to be heat-sealed of the air-permeable sheet, the air-permeable cushioning sheet and the air-permeable film are sealed in a state of facing each other to form a side portion and a bottom portion to form a bag shape, Next, a method for producing a cushioning sheet containing a powdered medicine, characterized in that an upper part of the bag is sealed after supplying the powdered medicine into the bag, and between the foaming cushioning sheet and the breathable membrane. A device for manufacturing a buffering sheet containing a powdery drug, which comprises heat-sealing after enclosing a powdery drug, wherein a heating crushing means for previously crushing air bubbles at a position to be heat-sealed of the cellular buffering sheet. , The Sealing means for sealing the foam cushioning sheet and the breathable film in a state of facing each other, and a drug for supplying a powdered drug into a bag formed by sealing the foam cushioning sheet and the breathable film An apparatus for manufacturing a buffer sheet containing a powdery medicine is provided, which comprises: a supply unit.

[Operation] One of the important features of the present invention is to crush the air bubbles at the position to be heat-sealed in advance when heat-sealing the air-permeable cushioning sheet and the breathable film. That is, when heat-sealing the bubble-absorbing buffer sheet and the breathable film, if there is a bubble portion between the heat-sealing layers, for example, the heat-seal bar causes the bubble-buffering sheet or the breathable film to be fused by heat, Sealing becomes difficult. Therefore, it is necessary to flatten the air bubbles at the position to be heat-sealed by crushing them with a preheated bar or the like. The temperature of the bar at this time is not limited, but generally 75 to 150 ° C is suitable. The heat sealing is preferably performed from the side of the material having a higher melting point.

Further, the heat sealing method of crushing the bubble portion by the impulse sealing method in which the material is sufficiently pressed and then the current is heated is extremely effective.

EXAMPLES Hereinafter, the present invention will be described in more detail with reference to the illustrated examples, but the present invention is not limited to these examples.

FIG. 1 is a schematic view showing an embodiment of a cushioning sheet manufacturing apparatus of the present invention, wherein 1 is a roll supply for storing a roll-shaped roll 1a of a foam cushioning sheet and 2 is a bubble buffer. 4 shows a heating and pressing mechanism for previously crushing air bubbles in a sealed portion of the flexible sheet. 3 is the original supply of breathable membrane,
Reference numeral 4 is a heat sealer for sealing the air bubble cushioning sheet and the air permeable membrane, 6 is a medicine hopper, 7 is a measuring mechanism, and 8 is a charging nozzle.

Next, the manufacturing procedure in the manufacturing apparatus for the foam cushioning sheet will be described with reference to FIG.

(1) The roll-shaped raw fabric 1a of the foamed cushioning sheet is fed from the raw fabric supply 1, and then, in order to prevent the seal from breaking, the heat-pressing mechanism 2 crushes the bubbles at the position where the seal is broken.

(2) The roll-shaped raw fabric 3a of the breathable film is fed from the raw fabric supply 3, and is first sealed in the lateral direction by the heat sealer 4 so that the bubbles are inside when facing the cellular cushioning sheet. 1 pitch, and the vertical seal is 2 pitches, and is formed into a bag shape having side and bottom surfaces.

(3) The fed-out sheet is tact-fed by the air cylinder 5 provided with a position detecting function so that the fed-out sheet is accurately fed at the same pitch.

(4) The powdered medicine in the medicine hopper 6 is measured from above on the raw material which is formed into a bag shape by vertically and horizontally sealed.
In order to prevent the medicine from remaining in the charging nozzle 8, the medicine in the charging nozzle 8 is completely dropped by the pecking rod 9 and the knocker 10.

(5) After the medicine is put into the bag-shaped original fabric, the original fabric is accurately fed by one tact by the air cylinder 5 and is vertically and horizontally sealed by the heat sealer 4, and the medicine is filled and sealed inside. The resulting cushioning sheet is manufactured.

(6) By performing the above steps intermittently, the buffer sheet in which the medicine is enclosed is cut into a desired width by a trimming slitter or the like, and stored in the storage container 11 as a packaged product.

The manufacturing procedure of the foam cushioning sheet has been described above with reference to FIG.

First, the injection nozzle 8 will be described. A large diameter is desirable for dropping the medicine, but a solid and thick injection nozzle is used during or after sealing overlapping sheets (foam buffer sheet and breathable film). If 8 is inserted from above or sealed while inserted, the seal portion will break. Therefore, in order to prevent this, it is preferable to use a cylindrical injection nozzle made of a flexible material.

In addition, the heating and pressing mechanism 2 is a bubble crushing mechanism used for crushing the bubbles at the position corresponding to the heat-sealing portion of the bubble-absorbing cushioning sheet by using an air cylinder or the like to flatten and improve the heat-sealing property. Is.

FIG. 2 is a partially enlarged perspective view showing an example of the heat sealer 4, where (a) shows a vertical sealer and (b) shows a horizontal sealer. The heat sealer 4 is a mechanism for heat-sealing the air-permeable cushioning sheet and the air-permeable membrane to which the medicine has been supplied, for example, a plate heater, a cartridge heater,
Alternatively, it is a mechanism for heat-sealing a heat-sealing bar 20 having a heat source such as an impulse heater by pressure-bonding it to the sealing portion with an air cylinder 21 or the like.

In FIG. 2, an impulse heater having a seal heater wire 22 is used, and a method for separately performing longitudinal and lateral sealing is shown in terms of the mechanism.

[Effects of the Invention] As described above, according to the manufacturing method and the manufacturing apparatus for the powdery drug-containing buffer sheet of the present invention, it is possible to manufacture the drug-containing buffer sheet in which the drug is completely filled and sealed. it can.
